β¦ Synopsis
This article presents a complete procedure to optimize microwave planar circuits with a rigorous electromagnetic approach. It dynamically combines intensive electromagnetic simulation with data interpolation. Various shielded microstrip stub configurations are optimized in the millimeter range. Results are compared with those provided by HP MDS, a commercial circuit simulator. 0 1996 John Wley & Sons, Inc. jects with cracks, this hybrid method is also available. A disadvantage is that an approximation is made in constructing integral equations for the equivalent magnetic current. This is being revised.
